Many people ask about the proper storage temperature for olive oil. Heat speeds up all of the above reactions. Keeping your oil next to the stove in a clear bottle will quickly age it. Better to keep a large container in a dark, cool cupboard and pour a small amount into a dispenser for everyday use. Olive oil can be put into the refrigerator or freezer without harm, which will greatly extend its shelf life. Waxes in the oil may crystallize out into needles or a slurry when the oil is chilled. Warming the oil back to room temperature will re-liquefy it.
